An electronic apparatus and a roll screen apparatus according to an embodiment of the present application are described below with reference to fig. 1 to 6.

As shown in fig. 1-4, an electronic device according to some embodiments of the present application includes:

a first bracket 1, a second bracket 2 and a driving piece,

the first support 1 and the second support 2 move relatively, the first support 1 has a first comb-tooth structure 11 extending along the moving direction, the second support 2 has a second comb-tooth structure 21 extending along the moving direction, and the first comb-tooth structure 11 and the second comb-tooth structure 21 are relatively staggered,

the driving part comprises a first magnetic assembly and a second magnetic assembly, the first magnetic assembly is arranged on the first comb tooth structure 11, and the second magnetic assembly is arranged on the second comb tooth structure 21;

with the first magnetic assembly in the first state, the first magnetic assembly interacts with the second magnetic assembly to move the first bracket 1 away from the second bracket 2;

in the second state, the first magnetic assembly interacts with the second magnetic assembly to bring the first support 1 into proximity with the second support 2.

In this embodiment, the first magnetic assembly and the second magnetic assembly act to drive the first bracket 1 and the second bracket 2 to move relatively, so that the first bracket 1 and the second bracket 2 can be far away from and close to each other, the first bracket 1 is driven to move relative to the second bracket 2 by the first magnetic assembly and the second magnetic assembly, excessive structures do not need to be arranged, the occupied space is smaller, and noise is not easy to generate.

For example, the action relationship between the first magnetic assembly and the second magnetic assembly is adjusted to enable the first magnetic assembly and the second magnetic assembly to generate different magnetic force actions in the first state and the second state, so that the effect that the first magnetic assembly and the second magnetic assembly can generate relative movement far away from or close to each other is achieved.

Optionally, the electronic device has a drive zone 10, the driving member being arranged within the drive zone 10. This allows to concentrate the structure of the drive member in a smaller area, reducing the space occupied by the drive member. For example, in the drive region 10, the first comb-tooth structure 11 is provided with a first magnetic assembly, and the second comb-tooth structure 21 is provided with a second magnetic assembly.

In one embodiment, as shown in fig. 2 to 6, the first magnetic assembly includes a first electromagnetic coil 121, at least one first electromagnetic coil 121 is disposed on each side of the first comb-tooth structure 11, and the first electromagnetic coil 121 is connected to an alternating current. The first electromagnetic coils 121 on both sides of the first comb tooth structure 11 are symmetrically arranged.

The second magnetic assembly includes two sets of magnetic groups, each magnetic group includes a plurality of magnets 22 sequentially arranged along the movement direction of the first comb-tooth structure 11, the magnetic poles of the plurality of magnets 22 facing the first electromagnetic coil 121 are arranged in a manner that N poles are spaced from S poles, the first comb-tooth structure 11 is located between the two sets of magnetic groups, and the end of the first electromagnetic coil 121 is opposite to the magnets 22.

In the embodiment of the present application, the first electromagnetic coil 121 on both sides of the first comb tooth structure 11 acts with the magnetic group, so as to achieve the effect of driving the first electromagnetic coil 121 to move through the magnet 22 in the magnetic group. The first electromagnetic coil 121 is disposed on the first comb structure 11, so that the magnetic assembly can drive the first comb structure 11 to move, thereby driving the first support 1 to move relative to the second support 2.

As shown in fig. 2, the end of the first electromagnetic coil 121 faces the side where the magnets 22 are arranged. The magnetic pole of the first electromagnetic coil 121 at the end facing the magnetic body 22 can be changed by applying an alternating current.

As shown in fig. 5 and 6, by changing the magnetic pole of the end portion of the first electromagnetic coil 121 opposite to the magnetic body 22 and adjusting the magnetic pole relationship between the magnetic pole of the first electromagnetic coil 121 and the magnetic body 22, the first electromagnetic coil 121 can move the first comb tooth structure 11 by the attraction and repulsion effect between the magnetic poles.

Taking fig. 5 as an example, the cooperation between the upper magnetic group and the first electromagnetic coil 121 is described. First, the magnetic pole of the first electromagnetic coil 121 toward the magnet 22 is an N pole, which is attracted to the S pole of the magnet 22 of the magnetic group biased to the left of the first electromagnetic coil 121, and the N pole is repelled from the N pole of the magnetic group biased to the right of the first electromagnetic coil 121, thereby magnetically driving the first electromagnetic coil 121 to move to the left.

When the first electromagnetic coil 121 moves to the left, the magnetic pole direction of the first electromagnetic coil 121 is changed. The magnetic pole of the first electromagnetic coil 121 facing the magnet 22 is an S pole, which is attracted to the N pole of the magnet 22 of the magnetic group biased to the left of the first electromagnetic coil 121, and the S pole is repelled from the S pole of the magnet group biased to the right of the first electromagnetic coil 121, so that the first electromagnetic coil 121 is driven to move to the left by magnetic force. The first solenoid coil 121 can be continuously moved to the left side by cycling the above process.

Referring to fig. 6, first electromagnetic coil 121 can be moved to the right side as in the principle of fig. 5.

Optionally, the first magnetic assembly further includes a second electromagnetic coil 122, at least one second electromagnetic coil 122 is disposed on each of two sides of the first comb tooth structure 11, and the second electromagnetic coil 122 is connected with an alternating current. The second electromagnetic coils 122 on both sides of the first comb-tooth structure 11 are symmetrically arranged.

The second electromagnetic coils 122 on each side of the first comb tooth structure 11 are arranged in a staggered manner with the first electromagnetic coils 121, and the directions of the applied currents of the second electromagnetic coils 122 and the first electromagnetic coils 121 are opposite.

For example, the first electromagnetic coil 121 and the second electromagnetic coil 122 constitute a coil assembly 12.

Taking fig. 5 as an example, only an example in which one first electromagnetic coil 121 and one second electromagnetic coil 122 are provided on each side of the first comb-tooth structure 11 is shown. The upper magnetic set is described in conjunction with the coil set 12. First, the magnetic pole of the first electromagnetic coil 121 toward the magnet 22 is an N pole, which is attracted to the S pole of the magnet 22 of the magnetic group biased to the left of the first electromagnetic coil 121, and the N pole is repelled from the N pole of the magnetic group biased to the right of the first electromagnetic coil 121, thereby magnetically driving the first electromagnetic coil 121 to move to the left. Meanwhile, the magnetic pole of the second electromagnetic coil 122 facing the magnet 22 is an S pole, which is attracted to the N pole of the magnet 22 of the magnetic group biased to the left of the second electromagnetic coil 122, and which is repelled from the S pole of the magnetic group biased to the right of the second electromagnetic coil 122, so that the second electromagnetic coil 122 is magnetically driven to move to the left.

When the coil assembly 12 moves to the left, the magnetic pole directions of the first and second electromagnetic coils 121 and 122 are then changed. The magnetic pole of the first electromagnetic coil 121 facing the magnet 22 is an S pole, which is attracted to the N pole of the magnet 22 of the magnetic group biased to the left of the first electromagnetic coil 121, and the S pole is repelled from the S pole of the magnet group biased to the right of the first electromagnetic coil 121, so that the first electromagnetic coil 121 is driven to move to the left by magnetic force.

Meanwhile, the magnetic pole of the second electromagnetic coil 122 toward the magnet 22 is the N-pole. The N pole is attracted to the S pole of the magnet 22 of the magnetic group biased to the left of the second electromagnetic coil 122, and the N pole is repelled from the N pole of the magnetic group biased to the right of the second electromagnetic coil 122, so that the second electromagnetic coil 122 is magnetically driven to move to the left.

The coil assembly 12 can be continuously moved to the left side by cycling through the above process.

Referring to fig. 6, the coil assembly 12 can be moved to the right side as in the principle of fig. 5.

Alternatively, as shown in fig. 3 and 4, two sides of the first comb structure 11 are respectively provided with a first arm, and the first electromagnetic coil 121 is wound around the first arms. The first support arm provides support for the first electromagnetic coil 121, and ensures that the first electromagnetic coil 121 has a stable structure in the moving process.

Optionally, two sides of the first comb structure 11 are respectively provided with a second arm, and the second electromagnetic coil 122 is wound around the second arm. The first support arm and the second support arm form a support arm group 13.

The set of arms 13 provides support for the coil set 12. For example, first and second support arms extend from the first bracket 11 toward the magnet 22 to hold the ends of the first and second electromagnetic coils 121 and 122 toward the magnet 22. This ensures the accuracy of pole fitting of the coil assembly 12 with the magnet 22.

In one embodiment, sliding grooves are formed between the adjacent second comb-tooth structures 21, and each first comb-tooth structure 11 is embedded in one sliding groove;

the sliding chute comprises a first chute body 211 and a second chute body 212, and the second chute body 212 is arranged on the bottom surface of the first chute body 211;

first broach structure includes broach main part 111 and broach boss 112, broach boss 112 is located the bottom surface of broach main part 111, broach main part 111 is located in first cell body 211, broach boss 112 is located in second cell body 212.

The first electromagnetic coils 121 are located on two sides of the comb main body, and the magnetic groups are located on the side walls of the first slot body 211.

In this embodiment, the first comb tooth structure 11 is movable within the chute. The comb tooth main body 111 is fitted with the first tank body 211 to move the comb tooth main body 111 along the inside of the first tank body 211 in the moving process. The comb tooth bosses 112 cooperate with the second slot 212 to move the comb tooth bosses 112 along the second slot 212 during movement. As shown in fig. 4, the first arms at both sides of the first comb structure 11, the comb main body 111 and the comb bosses 112 form a T-shaped structure. The structure surface of the structure composed of the second support arms at the two sides of the first comb tooth structure 11, the comb tooth main body 111 and the comb tooth bosses 112 is in a T shape. The first slot 211 and the second slot 212 are matched with the T shape. Therefore, the stability of the first comb tooth structure 11 and the sliding groove in matched movement can be improved.

In one embodiment, the first magnetic assembly is located at the side of the comb body 111, and the second magnetic assembly is located at the side wall of the first groove 211.

In this embodiment, the first magnetic member and the second magnetic member cooperate to enable the comb tooth main body 111 to move along the first groove body 211 under the action of magnetic force. The engagement of the comb bosses 112 with the second slots 212 can restrict the displacement of the comb main body 111 within the first slots 211 to be stable during movement.

For example, as shown in fig. 4, coil groups 12 are provided on both sides of the comb tooth main body 111, and magnetic groups are provided on the side walls on both sides of the first groove body 211. The coil groups 12 on both sides of the comb main body 111 are matched with the magnetic groups, so that the magnetic groups and the coil groups 12 act to drive the comb main body 111 to move. The comb tooth boss 112 is located in the second slot 212, so that the situation that the comb tooth main body 111 deviates to the magnetic groups on two sides in the process of magnetic pole adsorption and repulsion can be avoided.

Alternatively, the two coil groups 12 assume a position-symmetrical structure about the axis with the moving direction as the axis.

This enables the same magnetic force to be formed on both sides of the first comb tooth structure 11, further avoiding offset. For example, the oppositely disposed electromagnetic coils in the two side coil groups 12 simultaneously form an attraction force or a repulsion force with the two side coil groups.

In one embodiment, each of the first comb-tooth structures 11 is provided with the first magnetic assembly, and the sliding groove corresponding to the first comb-tooth structure 11 is provided with the second magnetic assembly.

In this embodiment, each of the first comb-tooth structures 11 and the sliding grooves can provide a driving effect, which improves the driving force when the first frame 1 and the second frame 2 approach and separate from each other, and facilitates the movement.
